. 4 Claims.

My invention relates to improvements in copyholders, particularly in copyholder types that use a casing or retainer to retain the paper before it passes a line marker. Such copyholders, are used by typewriter or key punch operators.

My invention will be understood by reference to the accompanying drawings, where the same parts are indicated by the same numerals throughout the several views.

Fig. 1 is a front view of the copyholder with the paper holding members closed.

Fig. 2 is a side view with the paper holding mechanism closed.

Fig. 3 is a side view of a somewhat differently shaped retainer with the paper holding mechanism open Fig. 4 is a side view having the front part of the casing removed.

Fig. 5 is a side view of a curved retainer.

Fig. 6 is a face view of a metal plate which supports some of the mechanism, a in Fig. 3.

Fig. 7 is a fragmentary rear view of the device shown in Fig. 4. r

The copyholder showsthe application of a paper retainer I in combination with paper feeding rollers 2 and 3. The paper retainer l is back of the paper feeding meansand has an open space 4 in front which can be used as a cardholder. The paper retainer I may be made of one piece ofsheet metal as illustrated in Fig. 3 or out of an outer piece and an inside piece or pieces 5 and 6. 6 is a slanting piece going from point D to point E. The outside metal piece I may also go straight over from point D to point F. In this case an inside metal piece 6 is necessary, but itis not necessary that such an inside metal piece 6 be connected between points E and F.

Inside piece 5 has at one end piece 1, which piece may also be a part of the outside piece I, as seen in Fig. 3.

With other words slanting pieces 6 and 1 lead the paper first up to point D. The paper inserted in the retainer at point G is flexible. As soon as the paper touches point D in the retainer, a further pushing of the paper into the retainer will fold the paper at point H and the paper inside the retainer will form the shape of an S. It is easily understood that a retainer which forms the paper to an S shape will take care of extralength in paper forms. For normal size sheets it is therefore possible to make the part of the retainer that forms the 8 paper shape muchsmaller in height and size than shown in the drawings. V

Quite important is also piece 8 which goes straight down from point J of the retainer. The straight piece 8 has at its end a round end 9 which will hold the paper inside the retainer in of the copyholder between points L and M. The l I retainer is supported'by plate II which is of the same width as the retainer and is itself supported in the rear by bar l3. Bar l3 has on both ends side piece l4. These side pieces, preferably in a forward slanting position support the paperfeeding mechanism and give also support by a horizontal bar l5, which is attached to the paper retainer, to the paper retainer itself. The paper retainer which is in its outside form shaped like an M in cross section, is absolutely independent from the paper feeding mechanism and in no way connected with it.

It is the combination between an independently working paper feeding mechanism and a casing or means that fold the paper in S shape and hold the paper upwards before it passes the feeding mechanism, like shown in Fig. 4 that is the main object of my invention. To illustrate the independence of the paper feeding mechanism from the paper casing, this casing may well be attached 1 inch or more backwards. away from the feeding mechanism as shown in Fig. 4. This has the advantage that a bunch of papers N may be arranged inside the retainer. The copyholder will then be turned around so that the eye of the operator will looklike illustrated in Fig. 4 and see each line at point 0. Fig. 4 also shows a line'marker P that can be folded upwards and may have an attachment Q. If many sheets are inserted in the paper feeding mechanism the attachment Q will stop these papers from moving forward and only the first sheet that is taken outside the attachment Q by hand will slide forwards when the paperfeeding mecha nism is moved.

When the frame that holds th paper feeding mechanism is rigidly connected with thetop of the retainer, frame and retainer support each other. This is obvious, as a casing that is substantially square in its outer form could easily be pressed out of shape and on the other hand the casing gives strength by its connection to the forwardly inclined frame of I the feeding mechanism. The feeding mechanism is entirely supported by a frame. This frame consisting .sidewards.

' have to be replaced by new ones.

of forward slanting side pieces 14 and bottom 3 bar I3 with rubber feet far apart and the top bar 1 l5, which serves as paper guide. the metal piece that is attached on each side l i of the frame. Through them, placed in the up- Fig. 6 shows per part of the side pieces l4 goes shaft IS with rubber'rollers 2 and handwheel H. Shaft I6 is supported by the same metal piece l8 which is fastened to piece M on each side of the frame 1 through holes [.9 and 20.. Hole. L9 is. the. turn ing point for piece: 2| and hole 201s: the turning;

point for piece 22. Piece 2| and 22 are connected by piece 23. By pressing piece 2lupl wards, the connecting piece 23 will turn piece 2-2 downwards. rubber rollers 3. These rubber rollers aremounted on steel bushings so that they canturn freely Piece 22 supports shaft 25 withf on shaft 25. When larger size sheets are to be copied with the copyholder the rubber rollers. are arranged in the following way. Four rubber rollers are mounted solidly on the driving shaft the copyholder in back of punching machines,

1 a hole 29 is provided in plate I I.

Fig. shows a curved casing. Two or more of such curved parts 3! may replace. the retainer shown at I in Figs. 1 and 2 when the same copyholder for a lower price and for normal length paper sheets is desired. In this case piece 8 as shown in Fig. 2 will be left away.

Fig.4.. The feeding device stays open until it is closed again by hand. As shown in Fig. 3 there is: plenty of; space. between the opened feeding rollers- Whenthe insid retainer 5 is not reand four rubber rollers are mounted solidly on the idle, shaft. The idle shaft may be moved As only two rubber rollers have an. opposite partner and the other two rubber rollers have the. opposite partner somewhat. on the left or right. side, the moving of the idle shaft sidewards will engage the: rubber rollers. that: were] single. before and. will separate the rubber rollers. that were. engaged before. I

Fig. 1 shows only two rubber rollers. on the idle shaft with the idea that. these rollers can; be moved'inside from R to S.

On piece 2! is. attached line marker. 26;; and I bar 21.. Thi bar 21. will hold the paper in up ward position and will at. the. same time serve as convenient handle to open and close the mechanism. 7 1

The driving shaft may be held in positionon, one. end by a screw with a pinz. When the screw is opened the (pin slides out of the driving: shaft} which makes it easy to remove: thedriving shaft. from the copyholder. when the'old; rubber rollers Another tea-- ture'of. my invention. i that the movable. piece 22 may be mounted at. its turning point 20 on an eccentric bolt. By adjusting this eccentric. bolt the pointy where rubber rollers 3 touch rubber rollers 2 will b changed according-1y. When.v the rubber rollers 3 are underneath the horizontal middle line of rubber rollers 2 the paper: will fall forwards. as soon as it passes these rollers. When the rubber rollers 3- are somewhat. above thehorizontal middle line of rubber rollers. 2 thepaper will fall backwards, as soon as it. passes these rollers. This feature makes it. possible to use the same copyholder looking, as indicated on'Fig, 3 from. the. front, or in Fig- 5 from the back; without. needing extra paper guides.

For sheets where the last line is very near the bottom of. the page an extra line marker pivotal. on its supporting; piece 28 is placed underneath piece 22in such a way that. when piece 22 is moved downwards, piece 28 moves downwards. too. Piece 28 will be adjusted toits normal position by pushing itupwards by hand. i Another feature. of my invention is that. whenthe mechanism is opened it stays. open by itself; this is attained by having in its open position the turning. points of connecting piece 23;. and the turning point of piece 2t in. a straight line as. shown in Fig. 3. Spring 2'4 shown in Fig. 4 will. close. the mechanism as'soon. as bar 21. movedforward. v'lo make it. possible to attach moved along sheet of paper may be pressed so far; into; the retainer. that it forms inside. the retainer the shape of. an v8.. The: upper part: of the. paper is thenpushed underneath line marker 26 or line marker 26 is removed and line marker,- 30 is used instead as-previously stated. Attention is given tothe fact that the first line on the paper has to, be perfect: line; with the: line marker. The paper; is then held firmly and the other hand gives to the: line marker awforwardl movement, whereby the feeding rollers: close. immediately andthe line marker snaps to its forward. position. Now the lines of the: inserted paper can be made visible along; the line: marker by turning the handwheel which may be attachedto. either side; of. the feeding roller.

When the inside retainer is removed. as; shown. in Fig. 4,. a bunch-.- of .papersheets may be'placed in the copyholder. The operator: may then: in!

sert a single sheet. at. a time. as shown in. Fig. 4

having turned before: the copyholder around sothat the view on the papersheet is: from the: back. The procedure to. feedv the paper with the paper feeding rollers is the: same as: stated. before, unless the wholev bunch is inserted at. one time between the feeding rollers. In such'a' case it is. necessaryqto separate the first paper from. the bunch by turning, thefe'eding rollers} firstbackwards and. thenforwards; The backward: movement. of the feeding rollers. will first turnthe firstsheet-away from the. paper stop' T (thev paper. stop: 'I. prevents the paper bunch from.

moving) whereupon. it is; easy to bend the: firstv page away from. the paper bunch; so that: a forward movement of the; feeding rollers slide the. first paper over stop T..

Having thus'described my invention;- what. I. claim and desire: to: secure by Letters; Patent. of the United States is:

i. In a copyholder a paper retainer for storing a plurality of sheets: inside the copyholder structure with means preferably strips. in back of the paper: retainer to lead the. sheets. upwards and then. away from the backwal l of the retainer towards: the middle of the retainer and; then backwards again to a stop. whereby a fold;-
